VAR_INPUT
MP_Address : USINT := 1;
bStart : BOOL;
bRead_Write : BOOL;
strDataKL6771 : DataKL6771;
nUnitSelection_Write : E_MP_EP_R_R6_UnitSel;
bControlMode_Write : BOOL;
rVmaxSeq1_Write : LREAL;
rVmaxSeq2_Write : LREAL;
MP_Address: MP-Bus address of the slave.
bStart: a positive edge starts the function block. If this remains continuously TRUE, the function block will be
activated cyclically with a period specified by the time in TMPolling .
bRead_Write: if FALSE then READ only; if TRUE then READ and WRITE.
strDataKL6771: the data structure with which the KL6771 [ } 25] function block must be linked (see
DataKL6771 [ } 72] ).
nUnitSelection_Write: scaling for rAbsoluteFlow_UnitSel (see E_MP_EP_R_R6_UnitSel [
}
66] ).
bControlMode_Write: FALSE: position-controlled, TRUE: flow-controlled.
rVmaxSeq1_Write: 0...100 %.
rVmaxSeq2_Write: 0...100 %.
VAR_OUTPUT
bBusy : BOOL;
bError : BOOL;
iErrorId : MP_Error;
strMP_Serial_Number : MP_Serial_Number;
nUnitSelection_Read : E_MP_EP_R_R6_UnitSel;
bControlMode_Read : BOOL;
rVmaxSeq1_Read : LREAL;
rVmaxSeq2_Read : LREAL;
rAbsVnom_InitSel : LREAL;
rAbsVnom_l_h : LREAL;
rAbsVnom_gpm : LREAL;
bBusy: this bit is set for as long as the function block is active.
bError: the output becomes TRUE as soon as an error occurs. This error is described via the iErrorId
variable.
iErrorId: this output outputs an error code in the event of an error (see MP_Error [ } 70] ). bError goes TRUE
at the same time.
strMP_Serial_Number: structure for the serial number. (see MP_Serial_Number [
}
73] ).
nUnitSelection_Read: set the scaling (see E_MP_EP_R_R6_UnitSel).
bControlMode_Read: FALSE: position-controlled, TRUE: flow-controlled.
rVmaxSeq1_Read: maximum sequence speed 1 in % (0...100 %).
rVmaxSeq2_Read: maximum sequence speed 2 in % (0...100 %).
rAbsVnom_InitSel: nominal volume (see rAbsoluteFlow_UnitSel ).
rAbsVnom_l_h: nominal volume in l/h (0...4294967295).
rAbsVnom_gpm: nominal volume in gpm (0...4294967295).
